Low-priced buying and averaging down? Don't borrow to hold on | Lee Jaegyu, SK Securities PB Deputy Manager [Today's Focus Stock]

Summary

SK Securities PB Deputy Manager Lee Jaegyu analyzes the sharp KOSPI/KOSDAQ decline through a volume-exhaustion lens, arguing that plummeting trading value and improving foreign buying signal a potential rebound. He highlights differences in credit balances between the two boards, sees large-cap beaten-down KOSPI stocks as attractive, identifies a positive AI catalyst for Korean memory chips, and advises trimming Samsung Electronics and SK hynix for investors with overly high average purchase prices while warning against the use of margin.

• KOSPI and KOSDAQ have fallen with sharply declining trading volume, a classic bottoming pattern.
• Foreign investors have turned to net buying in KOSPI spot and futures, with equity fund inflows improving.
• KOSDAQ credit balances collapsed faster, suggesting less selling pressure on a rebound.
• Super-large-cap KOSPI stocks that are down 40–50% offer the best rebound potential.
• The 'Moon Shot' AI model event is actually a positive catalyst for Korean memory companies like Samsung Electronics and SK hynix.
• Investors whose average purchase price in Samsung Electronics/SK hynix is near 190,000–200,000 won should consider trimming and re-entering later.
• Margin and leveraged trading should be avoided in this high-volatility environment; only cash should be used.
• US big tech earnings this week are a key short-term catalyst for the Korean market.
